tending lower end. It is understood, of eourse, that any type of truckor caster wheel construc- 1Jion could be utilized. A thrust collar 36positioned on the shaft 34 abuts the lower side of the portion 33 on thesupport 31, carrying the 1oad at that point. The shaft 34 is freelyrotatable With respect to the supporting member 31.

The draft tongue 37 is pivotal1y secured by bars 38 and 39 the ends ofthe pin 29, previously referred. to. By this construction the drafttongue may have up-and-down movement without transmitting such movementto any part of the planten Lateral movement of the tongue is transmitteddirectly to the main frame of the planter and the tongue truck iscarried around by such movement. A stay chain 40 is secured 1;0 theforward extension 33 of the truck supporting member and to a bracket 41secured to the tongue. j

A pair of bars 42, which form part of the depth adjusting means of theplanter, are pivotally comnected on the side bars of the main planterframe near the axle a short distance forwardly thereof. Said bars extendupwardly and inwardly to a point substantially over the auxiliary framewhere they are secured together by a tie holt 43. tie holt also forms apivot for a 1ink structure 44 which consists of two spaced members. Saidmembers have a curved portion for a purpose so be hereinafter described,which terminate in rearwardly directed portions. Said last namedportions are connected by a link 45 with a conventional band. adjusting1ever 46. Said lever is pivoted on the seat supporting bar 16, and anotch rack 47 is provided. for locking the lever in a'plurality ofadjusting positions. T0 assist the operator, in actuating the 1ever 46 arearwardly and downwardly extending bar 48, pivoted on the same axis asthe lever 46, is connected. by a bar The rear portion of the bar 48extends over the ax1e shaft 12 and is provided with a foot peda1 50within reach of ehe operator. Weight applied to the bar 48 assists theoperator in tilting the main frame of the planter for lifting the furrowopeners, as will be hereinafter explained. The forward portion 015 thebar 48 is connected by a link 51 pivoted thereto on a transverse axiswith a lifting member 52 secured 110 ehe auxiliary frame and extendingrearwardly therefrom. As illustrated, the link 51 extends through anopening in the member 52 and is provided. With a transverse pin 53beneath the member to provide for exerting upward pressure against saidmember. The weight 0f the furrow opener is normally suflicient to force113 into the ground the distance permitted by the adjustment 01 thelever. Conventional spring pres sure means may be utilized for thispurpose if found desirable.

The Same member which provides the rear. ward extension 52 on theauxiliary frame, extends forwardly and. upwardly to provide means forconnecting a lifting link 54. Said link is adjustably threaded through atrunnion block 55. 'Ifhe trunnions of said block are pivoted in alignedopenings in the structure 44 which, as previously described, consistsoftwo spaced members.

The forward ends of the bars 42 are pivotally connected on a transverseaxis to a supporting bracket 30' rigidly secured to the upper end of themember 31.

'Io provide means for lockinthe front supporting wheel against caseringduring operation of the planter in a straight 1ine travel, a 1atch isprovided. A se ctor 56 is rigidly secured to the Said top end of theshaft 34. A notch 57 is formed in the center of said sector. A 1atch bar58 pivoted on a transverse axis on the forward ends of the bars 42, ispositioned to engage said notch. A spring 59 is connected to the latchbar and to a forward. point on one of the bars 42 to hold the latchresiliently against the sector 56. A hairpin yoke 60 extends through anape1ptured lug on the 1atch bar 58 and rearwardly and downwardly towardthe 1ifting structure 44. The ends of the yoke are turned in 110rotatably hold a roller 61. Said roher runs on the circular portion ofehe structure 44 as a cam. When the lever 46 is oper2.ted to littthe"planter from operative position the Iatch bar 58 is withdrawn fromengagemem: with the notch 57, allowing the supporting wheel to freelycaster for turning the planter at the ends of the row.

Consideration cf the pivot points of the main frame on the auxiliary orfurrow opener supporting frame', the'pivots of the third frame with theauxiliary frame and with the front wheel support, the pivots of the bars42 on the main frame and the Support for the front wheel, and thevarious links connected thereto, will show that a substantially parallellitt arrangement has been provided. Throughout the entire range 0151ift, both with the furrow opener in the seil and above, a substantialrectilinear movement is obtained by the 1inkage provided. The movementis very free and a wide range of litt is obtained. The improved and.novel construction of ehe linkage illustrated and described, gives a-1ight weight planter which has all ehe desirable properties ofadjustment and operation.

Assuming that the planter is in lifted position, as shown in Figure 1the action of the lowering mechanism sah be briefiy described by directreference to the various members and links mak ing up the mechanism. Thelatch on the lever 46 is released by the operator and said 1ever ismoved forwardly. By this movement t'ne 1i nk 45 is moved forwardly,thereby rotating the structure 44 about its pivot on the tie holt 43.The lifting 1ink 54 is lowered by said rotation of the structure 44. Atthe same time the rear link 51 is 1owered. as the bar 48, to which it ispivotally connected, is rotated by operation of ehe lever 46. Thelehgths 01 the various links are so proportioned and. their pivot pointsare so located that a substantial rectilinear movement is 0D- tained. inthe inovement of the auxiliary frame.

The main frame 10 pivots forwardly during the lowering operation and theforward frame, which connects the tongue truck with the auxi1iary frame,pivots downwardly at its rear end. The liftingoperation is substantiallythe same, being brought about by pulling the 1ever 46 rearwardly. Theweightof the operator is applied t0 the pedal 50 assist in theoperation.

As previously described, the latch 58 engages the notch 57 in the sector56 and holds the caster wheel againsi. pivoting movement when theplanter is in ground engaging position. As shown in Figure 1, When thefurrow openers are lifted, the curved portion of thestructure 44operates as a cam 011 the roher 61 to draw the 1atch 58 out of engagingposition whereby the supporting wheel is free to caster for turning atthe ends of the fie1d.
